Episode 1 - For the last three decades, women have gone missing in Ciudad Juárez, Mexico, right across the border from El Paso, Texas. Some are found later, bearing the telltale signs of a serial killer. Hosts Oz Woloshyn and Mónica Ortiz Uribe begin their investigation into who could be responsible for these horrific crimes. We speak with the FBI’s former top agent on the border, as well as the journalist who’s gone the farthest in investigating the killings, Diana Washington Valdez.
